I currently live / work in Germany and have dual citizenship with the US and DE. I have a US student loan. How can I use my interest deduction this year or in the future?

Hi.  To claim your student loan interest on your tax return, type in student loan interest in the search box at the top of your screen and click the Jump to link.

It does not specify how to claim student loan interest against foreign-earned income or how to save the deductions for future years if I do not have US income at this time. Please advise and thank you!

You cannot save the loan interest deductions from  one year to the next.  You would have to have taxable income to be able to take the deduction.
